I wear contacts, and take them on backpack hunts.
I do carry a small mirror in case I need to take mine out & put them back in...............

The Brunton Compass I take with me has a mirror.
Calvin,
I wear two week contacts for 3-4 months. Take 'em out every nite dirty fingers or not. Gently clean them in my palm once every two weeks. There's no way I'm gonna pay the extra coin for extended wear lenses. No reason too, its a scam. I have worn mine for up to 4 straight days but I don't like to. I just happened to be that tired.
